Description

In reviewing the existing SSH profile we observe inconsistency the approach for what devices are being "generalized". Specifically, most devices are reified in the instanced data as cim:Equipment. For example:

<cim:Equipment rdf:about="#_c5aa8f57-82a4-4242-b093-2183cc6732b5">
<cim:Equipment.inService>true</cim:Equipment.inService>
</cim:Equipment>

However, in the case of Switches we have the specific specializations defined in the profile (Jumper, Breaker, etc). This should be changed such that these are removed and that all specialized of cim:Switch appear in the profile as:

<cim:Switch rdf:about="#_c5aa8f57-82a4-4242-b093-2183cc6732b5">
<cim:Equipment.inService>true</cim:Equipment.inService>
...
</cim:Switch>


Proposed Solution

Review the entire profile to address all unnecessary specializations within the profile definition. As a rule, the device should be declared at the "highest level" for which the needed SSH attributes appear in.

For example, in the case of Switches we have the specific specializations defined in the profile (Jumper, Breaker, etc). This should be changed such that these are removed and that all specialized of cim:Switch appear in the profile as:

<cim:Switch rdf:about="#_c5aa8f57-82a4-4242-b093-2183cc6732b5">
<cim:Equipment.inService>true</cim:Equipment.inService>
...
</cim:Switch>


Decision

17-Jan-2024:
In CIM18 (456-SSH) we will add in SSH all classes that inherit from Equipment and make Equipment abstract.

19-Sep-2024:
Revisited and gave the green light to implement and close this.
